rat(a^(r+1)) looks like aa^r, so there is no occurrence of r+1 at all. ratsubst(q-1,r,a^(r+1)) results in a^q, which is presumably the desired result. a^(2r+1) is a(a^r)^2 , so there is not a simple hack for making it a^q. Just use subst instead of ratsubst for exponents; ratsubst(a,b,c) works for a,b,c polynomials or rational functions, since it relies on CRE form (canonical rational expression) form, where division-with-remainder can be used to find subexpressions. Sometimes extracting kernels...
